A Roth conversion advisor is a retirement tax specialist who models and schedules IRA-to-Roth conversions across multiple years with the goal of reducing your total tax over your lifetime, not just this April’s bill. If you have already decided a conversion is probably worth doing, the real question is who should run it. Choosing a Roth conversion advisor comes down to three things: genuine specialization, a fiduciary standard, and a compensation model you understand well enough to see how your advisor is paid.
A Roth conversion advisor plans the timing and size of your IRA-to-Roth conversions over many years, coordinating tax brackets, IRMAA Medicare surcharges, Social Security taxation, and required minimum distributions. The candidates worth shortlisting are fiduciaries who specialize in conversions. Advisers are compensated in different ways, including a flat or fixed fee, an hourly rate, a percentage of assets under management, or commissions, so ask each candidate how they are paid.
What Is a Roth Conversion Advisor (and What Do They Actually Do)?
A Roth conversion advisor builds a multi-year plan for moving pre-tax IRA or 401(k) money into a Roth. That means bracket-fill modeling, IRMAA and Social Security coordination, RMD reduction, and heir analysis. It is a tax-projection discipline, distinct from a generalist who manages investments or a preparer who only files last year’s return.
Most people already have someone in their financial life: a broker, a wealth manager, or a CPA. A Roth conversion advisor does something narrower and deeper. Instead of asking “how do we invest this money,” the specialist asks “in which years, and in what amounts, should this pre-tax balance be converted so the total tax paid over your retirement and your heirs’ inheritance is as low as reasonably possible.”

Craig has helped IRA millionaires save over $1 million each in unnecessary taxes. Find out if a Roth conversion strategy fits your retirement, with no sales pressure and no product pitch.
That work typically includes:
- Multi-year conversion scheduling – a written year-by-year plan, not a single lump conversion.
- Bracket-fill / bracket-management modeling – converting enough to “fill” a target bracket without spilling into the next one. In 2026 the 22% bracket begins at $50,400 of taxable income for single filers and $100,800 for married filing jointly, and 37% starts at $640,600 single / $768,700 MFJ.
- IRMAA and Medicare surcharge management – a conversion raises your MAGI, and Medicare looks back two years to set premiums. In 2026 the first IRMAA tier begins above $109,000 (single) or $218,000 (joint), on top of the standard Part B premium of $202.90 per month.
- Social Security taxation timing – sequencing conversions so they do not needlessly push more of your benefit into taxable territory.
- RMD reduction – shrinking the pre-tax balance before required minimum distributions begin at age 73 (age 75 for those born in 1960 or later), when the IRS Uniform Lifetime Table applies a divisor of 26.5 at age 73.
- Capital-gains coordination – because ordinary-income conversions and long-term gains compete for the same bracket space, and because the 3.8% net investment income tax can apply above $200,000 (single) / $250,000 (joint).
- Heir and legacy analysis – modeling the widow’s-bracket problem (a surviving spouse filing single, often in a higher bracket) and the SECURE Act 10-year rule that forces most non-spouse heirs to drain an inherited IRA within a decade.
Roth conversion advisor vs. CPA vs. generic financial advisor
These roles overlap but are not interchangeable. A CPA or tax preparer is usually looking backward, filing the return for a year that has already happened, and most do not run forward multi-decade projections. A generalist financial advisor manages your portfolio and may mention Roth conversions, but conversion strategy is rarely their core competency. A dedicated Roth conversion advisor lives in the forward-looking tax model and coordinates with your CPA rather than replacing them.
The tools a real specialist uses
Ask what software a candidate runs. A retirement tax calculator you can find online is fine for a rough sanity check, but a real engagement relies on multi-year tax-projection software that models every future year: brackets, standard deduction (in 2026, $16,100 single / $32,200 MFJ, plus the age-65 addition and the OBBBA senior deduction of up to $6,000 per person for those 65 and older through 2028), IRMAA thresholds, Social Security inclusion, and RMDs. If the answer is “a spreadsheet” or “a single calculator,” you are likely looking at a generalist.
Do You Need a Roth Conversion Specialist, or Can You DIY?
You can DIY if your balances are modest and your income is stable. A specialist earns their fee when the stakes are large: high pre-tax balances, IRMAA exposure, Social Security timing, and heirs. The trade-off between an optimized multi-year plan and flat annual conversions can be material, but it depends entirely on your own facts and cannot be predicted in advance.
The gap between a good plan and a mediocre one is not small. The difference between an optimized, bracket-managed schedule and simply converting the same round number every year can be material for households with large pre-tax balances, but the outcome is specific to each situation and cannot be promised in advance. The risk runs both ways. Convert too little and you leave a future RMD problem intact. Convert too much in one year and you can trigger a needless jump in bracket, a two-year-lagged IRMAA surcharge, more taxable Social Security, reduced ACA premium subsidies, or less college financial aid through FAFSA. A conversion is ordinary income with no dollar or income limit, it must be completed by December 31 (not April 15), and since 2018 it cannot be undone, so there is no recharacterization safety net. Deciding how much to convert to a Roth each year and estimating the break-even point on the tax you prepay is exactly the analysis a specialist is built to run.
What the CRCS designation signals (and its limits)
You may see the Certified Roth Conversion Specialist (CRCS) credential in your search results. A designation signals that an advisor has studied conversion mechanics, which is a reasonable baseline. But most such credentials are marketed to advisors, not to the retiree hiring one, and initials alone do not prove judgment. Track record, a defensible analytical framework, and the fee model matter more than the letters after a name. When you review Craig Wear, CFP, founder of Q3 Advisors, for example, the relevant signals are the depth of focus on this one problem and a defensible analytical framework, not a single certificate.
When DIY software is enough vs. when to hire
DIY tools are reasonable when your pre-tax balance is small, your income is flat, you are comfortable reading a tax table, and you have no Medicare or Social Security interactions yet. Consider hiring when your combined IRA and 401(k) balances are large, you are within a few years of Medicare or RMD age, you expect a surviving spouse to face the widow’s bracket, or you want an early-retirement conversion ladder built around a specific income target.
Fee-Only, Fee-Based, and Commission: How Your Advisor’s Pay Model Can Affect Roth Decisions
Advisers are compensated in several ways. A commission-based adviser is paid by product manufacturers when you buy a product such as an annuity. An adviser charging a percentage of assets under management is paid based on the account balance. A flat-fee or fee-only adviser is paid a set fee directly by you. Ask any candidate how their compensation works.
The three compensation models explained
There are three broad ways an advisor gets paid, and the labels are easy to confuse:
| Model | How they are paid | How the fee relates to a conversion |
|---|---|---|
| Fee-only (flat / fixed) | A flat project or annual fee paid directly by you; no products, no asset-based cut | The fee is a set amount and does not change with how much you convert |
| Fee-only (AUM %) | A percentage of assets under management, often around 1% per year | The fee is calculated on the account balance, which decreases when tax is paid on a conversion |
| Fee-based | A blend of fees plus commissions on products sold | Compensation can combine an asset-based fee with commissions on products |
| Commission | Paid by the product manufacturer when you buy (for example, an annuity) | The adviser is paid when a product is purchased rather than for conversion modeling |
How different fee structures relate to the conversion decision
It helps to understand how each fee structure interacts with a conversion. When you convert, you pay income tax, and that tax money leaves the portfolio, reducing the balance. Under a percentage-of-assets model, the fee is calculated on the account balance, so after a large conversion the fee is applied to a smaller balance. Under a flat-fee arrangement, the fee is a set amount that does not change with the balance or with how much you convert. Under a commission model, the adviser is paid when you purchase a product. None of this tells you whether a given adviser will serve you well; it simply describes how the money works. Understanding how your adviser is paid lets you ask informed questions about any recommendation.
Flat-fee vs. 1% AUM: the 20-year cost math
Consider a hypothetical $2 million portfolio. A 1% annual AUM fee is about $20,000 in year one, and as the balance grows the dollar fee grows with it, reaching roughly $39,000 by year 20 on a portfolio that has grown to about $3.9 million. A one-time or flat-fee conversion engagement is a fixed cost that does not recur each year. The figures below are illustrative only and assume steady growth; your actual numbers will differ, and you can compare the two using your own balance and time horizon.
| Fee approach | Year 1 | Year 20 (approx.) | Nature of cost |
|---|---|---|---|
| 1% AUM on a $2M portfolio | ~$20,000 | ~$39,000 / year | Recurring, grows with the balance |
| Flat-fee conversion engagement | Typically $3,000-$15,000 | One-time or as re-engaged | Fixed, unrelated to balance |
How to Vet a Roth Conversion Advisor: 8 Questions to Ask
Before you hire, ask direct questions and listen for specifics. Good candidates answer plainly about their fee model, their software, and how they handle IRMAA, the TCJA/OBBBA rate landscape, capital gains, and heirs. Vague answers, product pitches, or discomfort discussing compensation are the red flags to watch for.
- Are you a fee-only fiduciary, and do you sell any products or manage assets for a percentage? A clear answer lets you see exactly how the adviser is compensated before you engage.
- Do you model IRMAA and the two-year Medicare look-back? If they do not know the current tier thresholds, conversions may cost you in premiums later.
- Do you build one plan for the scenario where tax rates rise and one where they stay level? The OBBBA (P.L. 119-21) made the 10% to 37% brackets permanent, but future law can still change; good planning stress-tests both paths.
- Do you treat capital gains and conversions as competing for the same bracket space? A specialist coordinates them; a generalist often does not.
- How do you decide how much to convert each year? Look for bracket-fill logic tied to your projected future rates, not a flat round number.
- How do you factor in my heirs and a surviving spouse? The 10-year inherited-IRA rule and the widow’s bracket should be part of the model.
- What software do you use, and can I see a sample multi-year projection? You want real year-by-year output, not a one-page calculator screenshot.
- What exactly do I receive, and what does it cost? A written schedule, projections, and a transparent fee should all be spelled out before you commit.
What Roth Conversion Consulting Should Include (and What to Expect It to Cost)
Roth conversion consulting should produce a written, multi-year conversion schedule backed by year-by-year tax projections, IRMAA and Social Security modeling, RMD analysis, coordination with your CPA, and periodic reviews. Flat-fee engagements commonly range from about $3,000 to $15,000, while AUM pricing typically runs around 1% of assets per year. Ask for the deliverables in writing before you pay.
A complete engagement should hand you more than a verbal opinion. Expect these deliverables:
- A written, year-by-year conversion schedule showing how much to convert and when.
- Multi-year tax projections that show the trade-off between paying tax now and later.
- IRMAA and Medicare surcharge modeling around the current tier thresholds.
- Social Security taxation timing analysis.
- RMD reduction modeling, including the age-73 start and the 2026 required minimum distribution rules.
- Coordination with your existing CPA or tax preparer at filing time.
- Annual (or periodic) reviews to adjust the plan as tax law and your income change.
On price, flat-fee conversion consulting commonly falls in the $3,000 to $15,000 range depending on complexity, while an AUM model charges roughly 1% of assets each year for as long as you stay. As an example of the flat-fee approach, Q3 Advisors offers our flat-fee Rothology Roth conversion service, which is priced as a fixed engagement rather than a percentage of your balance.
Should You Hire a Nationwide Specialist or a Local Advisor?
A Roth conversion is a tax-modeling problem, not a local one. Federal brackets, IRMAA, and RMD rules are the same in every state, so specialization and a demonstrated methodology usually matter more than a nearby office. Most dedicated conversion specialists work with clients nationwide by video and secure document sharing.
There is little tax advantage to sitting across a desk from your conversion advisor. The analysis is driven by federal rules and your own numbers, and it is delivered through screen-shared projections and written schedules. State income tax does factor into the model, but a competent specialist accounts for your state without needing to live in it. Prioritize depth of focus and a clear framework over a local address.

Frequently Asked Questions
What does a Roth conversion advisor do that my CPA does not?
A CPA usually files the return for a year that already happened. A Roth conversion advisor works forward, building a multi-year conversion schedule with bracket-fill modeling, IRMAA and Social Security coordination, RMD reduction, and heir analysis, then coordinates with your CPA at filing time. The two roles complement each other rather than compete.
How does an advisor’s compensation model affect Roth conversion advice?
How an advisor is paid is worth understanding before you hire. Compensation models include a flat or fixed fee, an hourly rate, a percentage of assets under management, and commissions on products. Under an asset-based fee, the amount is calculated on the account balance, which decreases when you pay tax on a conversion. Ask each candidate how they are paid and how their fee is calculated.
How much does Roth conversion consulting cost?
Flat-fee engagements commonly range from about $3,000 to $15,000 depending on complexity. An AUM model instead charges roughly 1% of assets each year, which on a $2 million portfolio is about $20,000 in year one and grows with the balance. An asset-based fee is charged every year, while a flat fee is typically a one-time or periodic cost, so you can compare the two using your own numbers.
Does the Certified Roth Conversion Specialist (CRCS) designation matter?
It signals baseline study of conversion mechanics, which is a reasonable starting point. But the credential is aimed at advisors, not the retiree hiring one, and initials do not prove judgment. Track record, a defensible analytical framework, and the fee model matter more than the letters after someone’s name.
Can I convert an inherited IRA to a Roth?
Generally no. A non-spouse beneficiary cannot convert an inherited IRA to a Roth and must follow the SECURE Act 10-year withdrawal rule. Only a surviving spouse who treats the inherited IRA as their own may then convert it. This is one reason heir and widow’s-bracket planning belongs in a conversion strategy.
When is the deadline to complete a Roth conversion?
A Roth conversion must be completed by December 31 of the tax year, not April 15. It counts as ordinary income with no dollar or income limit, and since 2018 it cannot be reversed, because recharacterization of conversions is no longer allowed. That irreversibility is why the amount and timing deserve careful modeling before you act.
What tax side-effects should a good advisor plan around?
A conversion raises your MAGI, which can reduce ACA premium subsidies and FAFSA aid, increase how much of your Social Security is taxed, and trigger IRMAA Medicare surcharges two years later. A capable advisor also plans the source of the tax payment and the risk of a market drop soon after a conversion. A weaker one misses these ripple effects.
Should I hire a nationwide Roth specialist or someone local?
Conversions are a federal tax-modeling problem, so specialization usually outweighs geography. Brackets, IRMAA, and RMD rules apply the same everywhere, and a good specialist accounts for your state tax without needing a local office. Most dedicated conversion advisors serve clients nationwide through video meetings and secure document sharing.
